I don't know if it will be the next few weeks but I think this "crisis" is past the point of diplomatic return. NK isn't going to stop and they keep doubling down. Trump and Matt is clearly stated multiple times it's not going to happen.So by mid August we should be well into WW3.
Its only a matter of time until someone's will is imposed on someone else.
It can't go on much more in its current situation. Every day tensions escalate and the rhetoric increases.
In my opinion it will go down like this in a series of incremental steps,
Nk will shoot off another ICBM
we will shoot it down or attempt to shoot it down
NK will not react well and will either test another nuke or shoot more missiles
Trump will say ok game over its on.
